Selection Aid for Victron Orion-Tr Smart Chargers and Converters
Deel
Choosing the right Victron Orion-Tr Smart charger or converter can sometimes be overwhelming, especially with the many variations available. In this article, we'll help you make the right choice for your camper installation. We'll discuss the main differences between the chargers and converters and provide practical tips to help you make the best choice.
What is the difference between a Victron Orion-Tr Smart Charger and Converter?
Orion-Tr Smart Charger:
- Battery charging function: The Charger is specifically designed to charge your house battery. It goes through various charging phases to ensure your battery is charged efficiently and safely.
- Application: Ideal for charging the house battery via your camper's or boat's alternator. We always recommend choosing the Charger when charging via the alternator, even if it is slightly more expensive than the Converter.
Orion-Tr Converter:
- Voltage conversion: The Converter is designed to convert voltage to a single constant voltage without a battery charging function. It is suitable for powering sensitive equipment that requires a stable voltage.
- Application: To be used when you want to provide specific equipment with a constant power source, but not intended for charging a battery.
Isolated or Non-Isolated: What is the difference?
- Non-Isolated: This is the standard choice for most campers. The Non-Isolated version is cheaper and sufficient for most applications, unless you have very sensitive equipment on board.

-
Isolated: In this version, the two DC circuits of the starter battery and the house battery are completely separated. This prevents possible malfunctions or interference. Choose this version when you use extremely sensitive equipment and want absolute certainty that the circuits are separated. The extra cost is definitely worth it in that case.
Choosing the right Orion-Tr Smart Charger: Current and compatibility
Current:
-
12V to 12V: Most campers have both a 12V starter battery and a 12V house battery. For this situation, the Orion-Tr Smart 12/12-30A Charger (360W) non-isolated is the most chosen option.
-
Heavier systems: Do you have a larger house battery (larger than 200Ah)? Then consider the Orion XS 12/12-50A DC-DC battery charger. This compact and efficient charger is perfect for larger installations where faster charging times are desired.

Compatibility:
- Always check if the charger is compatible with your vehicle's alternator. Especially with modern vehicles with a smart alternator, this is important to prevent overloading the system. However, the Orion-Tr Smart Chargers are well prepared for this and suitable for Euro 5 and 6 engines.
Settings and configuration via Victron Connect App
After installing your Orion-Tr Smart Charger, it is crucial to configure the correct settings via the VictronConnect App (Android and iOS):
- Set function: Make sure to set the function to 'Battery Charger'. By default, this function is set to 'Power Supply', which means the device acts as a converter and not as a charger. This can lead to the battery not being charged (properly), so it is important to adjust this immediately.
- Battery settings: Via the app, you can also set the battery type, so the charger works optimally for your specific battery.
Alternatives for a limited budget

For campers with a simple installation without a smart alternator, and using lead-acid batteries, a simpler system with a relay like the Victron Cyrix-ct 12/24V-120A intelligent combiner can be a good and affordable option. This system is cheaper to purchase and easy to install, suitable for older campers without Euro 5 or 6 engines.
Why choose a Victron Orion-Tr Smart Charger?
- Reliability: Victron is known for its reliable products that can withstand the demanding conditions that traveling with a camper can entail.
- Flexibility: With various options for current, isolation, and compatibility, Victron offers solutions for almost every situation.
- Ease of use: Thanks to the VictronConnect App, you can easily change settings and monitor your system, ensuring a carefree experience during your travels.
Conclusion
Choosing the right Victron Orion-Tr Smart charger or converter depends on your specific needs and the configuration of your camper. For most installations, we recommend the Orion-Tr Smart Charger. Don't forget to configure the correct settings via the VictronConnect App after installation, to ensure everything works correctly and efficiently.
